摘要
通过对一道习题的解析,利用微元法构造出不同的微元,解决了同一个待求总量的计算问题,帮助学生更深入地理解微元法的本质。
Some differential elements were constructed by infinitesimal method based on the analysis of a test question. It solved the same calculation problem of amount and helped the students with a deeper understanding of the nature of the infinitesimal method.
